y drawing.

This invention relates to improvements in gang plows and especially to improvements in gang plows in which the furrow forming elementsare disks. 'It will be understood, however, that my invention is not necessarily so limited.

One of the objects of the invention is to .provide a plow of this character which is especially well adapted for following and plowingat an even depth, ground which is more or less uneven and rolling in character. Another object is to provide imp roved means whereby the furrow forming elements may be lifted out of plowing positions and whereby this lifting of the furrow forming elements may be effected successively, beginning with those at the rear end. rIhe invention further contemplates the efl'ectingof the lifting automatically and by means of power. Other objects .will be apparent from the following specification and claims.`

In the accompanying drawings I have shown the embodiment of my invention which I now deem preferable. 'It will be understood, however, that numerous changes and modifications may be made.

-Fig l0 is a fragmentary diagrammatic View of the lifting cams taken from the righthand side of the machine. A

Referring to the drawings, it will be noted that the main frame as shown, comprises two principal parts, l and 2. 4As to the details of these frame parts, there may be variations but in the construction shown, the ,forward part, l, comprises a front cross-bar 3, and thevside bars 1L and The side-bar 4L extends rearward throughout a part of its length and is then bent inward to form the diagonal member 4a. tends rearward for a short distance and is then bent inward to form the diagonal element 5a. The rear ends of the diagonal ele'- ments il are joined at (l.

The'rear frame section 2 comprises a forward member 7 which is diagonally positioned parallel to the diagonal element 4a ofthe front frame.v The frame section 2 also has a diagonal element 8 wh1ch is connected at lts forward end to the rear end 'of the element 7 and which is positioned parallel to the element'nl of the front frame. A strut or brace l), connects the forward end of the element 7 with the rear part of the element 8.

The two frame sections are flexibly connected together by means of hinge devices at 1() and 10a.

While I have-shown inthe drawings but two framev sections, it will be understood that a larger number of sections may be used if found desirable. The manner of constructing and connecting such additional frame sections will be readily apparent.

Rigidly secured to the diagonal rear edge Patented May 22, 1917.

The side-bar 5 exy elements 5a and 8 of the framesections 1 andl 2,` are plowing or furrow forming ele- As shown, these plowing elements are rotatable disks which are connected to the frame parts by means o'f brackets 12-12. The disks canbe connected tothe brackets in any well-known or pre-A ferred manner and as this feature of the mechanism forms no part of my present linvention, detailed description can be,omitted.` As shown, the disks lil-11 are provided with Scrapers 13-43, but as to this feature also, there can Vbe variation. In fact, so far as certain features of my invention are concerned, the disks may be omitted entirely and plowing elements of the moldboard type substituted.

For supporting the forward corner of the front freine section, which is opposite to the.

y0n the axle 20. The axle 20 is connected with the lvertical spindle 2l, which is vertically slidable in a bearinglaperture in a pedestal 22, secured to the frame element 5. Mechanism is provided for movingv the spindle 21,'together with the axle 2O and the wheel 19, vertically with respect to the bracket. after described in detail. For preventing the axle Q0 and the wheel 19 from swinging about the axis ot' the spindle 2l, l provide the link or strut 2S, which can be adjust-ed in length by means of the turn-buckle 24C. ln this way the axle 20 can be moved and the angle ol the wheel, with respect to the line of draft7 can be varied as desired. s

.For supporting the rear' part ot' the from; frame section, I provide the third ground wheel 25, which is positioned at a`n angle to the vertical and so* located that it is adapted to travel in the furrow formed by the last disk on the front frame section. Thisv wheel 25, is mounted on an axle 2G which is connectedlto the` vertical spindle. 27. This spindle 27 is slidable in a vertical bearing` aperture in a pedestal 28, which is secured to the frame by means of the bracket ln the form shown, this bracket 29 is an extension of the bracket l2 for the rear disk. As to this feature, there can. be variation. Preferably the bracket 2S) is reinforced by the bar indicated at 30. The

.spindle 27 together with the axle 26 and the wheel 25, can be moved vertically with respect to the frame by means oiI mechanism similar to that for the spindle 2l. This meclianism will be linscribed later.

rlhe forward paA ks oi the rear frame seee tion 2 arc supported by means of' the. hinges l0 and lll which connect them to the front frame section. The rear part of the rear 'trame section is supportei'l by means oi' a ground wheel l, wl ch mounted by means ot' an axle 32 and a .spindle 3?), simi lar resl'iectively to the parts` 2li and 2. The spindle 325 is mounted in a pedestal 3i which is similar to the pedestal QS and similarly secured to the frame section. The wheel 8l can be moved vertically with respect to the.

trame section by mccl'ianism to beV described.

Secured to each of Vthe pedestals 22, 528

and is a horizontally extending' arm 35 to This mechanism will be herein' which is, pivotally connected the lower end oi a threaded rod 86. 37 is a yoke which 1s slidable on the rod 36 and which. can be adjusted by means of the threaded hand wheel 38. 39 is, a lever whichiis bifurcatedat its rear Vend and embraces the sleeve et() secured to the upper end of the spindle. The lever is pivoted .to the sleeve at 41. The rear end of the lever is ypivoted at L12 to the yoke 37 and a lug Lili-3 on the sleeve 40 serves to limit the movement of the lever in one direction. From the foregoing description it will be obvious that the downward movement or" the forward end of the lever will cause a corresponding downward movement of the spindle andof the wheel and axle with re spect to the pedestal. However, as the wheel is in contact with the ground the result will be a lifting of the pedestal and of the adj acent frame parts with respect to the wheel. The relative positions of the wheel and of the frame parts can be adjusted by mea-ns of the hand wheel 38. For holding the pedestal and trame parts in lifted positions, l provide a sprinheld latch 4:4 which is adapted to' engage asuitable lug on the sleeve d0. 'lila/ch latch ed is held by its spring either in opera-tive or inoperativel position as desiredA by the operator. 1When it is desired to hold the disks .in elevated position the latches are manually thrown into their operative posi tions. l The controlling` lever for the front wheel. 19 is indicated as betere noted, by 3S). The lever for the middle wheel 25 is indicated by 3Q, The leverl for the rear wheel til is indicated byf391. These 'levers can be operated manually by the plowman but l prefer to also provide means whereby the levers can be moved automatimxlly by power and moved successively. lifting' mechanism, there can be wide varia.- tion but 'for the purposeoic illustration, I have' shown a mechanism which is in many ,ir-sp1 `:ts similar to that shown and described in my earlier ifo-pending application for gang' plows, Serial No. (571,955, iiled Janu ary 18, i912. liefen-hip,v in detail to the lifting' mechanism l5 is a short jack shaft parallel. to the shaft '15, upon which thev ground wheel le is mounted. Loosely mounted on the jack shat't #l5 is a sprocket wheel 4-(3 in line with a sprocket wheel l-T on the shaft 15. A chain iid passes over these two wheels. Secured to the sprocket wheel i6 a notched or serrated disk dil and adjacent this disk and keyed to the sha lit l5 a. large circular disk :'(i termed at one point in its periphery with a rounded notch 5l.' A. do;y 52 is pivetally mounted on the disk 50. The head of the dog carries a laterally extending roller arranged to engage with 4the notched periphery cit the disk 9, and a spring'y 5a which is As to the details of this A llt) Leanser andthe dog 52, tends to press the roller 53 into engagement with the disk 49. A. lever is pivotally mounted on the bearing bracket beneath the disk 49 and carries a roller 57 adapted to ride upon the periphery ot said disk. The lever also carries the roller 58 which is disposed in the plane ot' the dog 52. 59 is a coil spring interposed between the end ot the lever 55 and an eX tension 69 oli the bearing bracket 56 and tends to press the roller 57 radially inward against the disk 50. The upper end of the lever 55 has connected to it al rope or cord 61, which extends forward to some convenient point within the reach of the operator.

By referring to Fig. 8 it will be seen that when the roller 57 lies within the notch 5l in the disk 50 the roller y58 is in position to engage the rounded back or tail of the dog 52 and swings the dog on its pivot so that the roller 53 is withdrawn from engagement with the continuously rotating notched disk 49. It now 'the driver pulls on. the rope 6l to swing the upper end of the lever 55 `torward, the rollers 57 and 58 will be swung downward and the spring 54 will expand and cause the dog 52 to -swing the roller 53 into engagement with the rotating disk 49. In this way a driving connection Vis effected between the disk t9 and the disk '50 so that the rotation of the former is transmitted to 'the latter.

The rotation of the disk 50 causes the notch 5l to he immediately rno'ved away from the roller 57 so that when the rope 6l is released by the driver and the spring 59 tends to return the lever 55 to its initial position, such a return is prevented. by the engagement or" the roller S17-with the circular periphery of the disk 59. But as the disk 50 nears the end of. its revolution the roller 57 ridessuddenly into the notch. .5l under the action of the spring 59 and in this movement the roller 584 is caused to strike the 'tail of the dog 52 and to cause the dis engagement of the roller 53 'from the disk t9.

Thus, by a simple pull upon the cord 6l,

the rotation of the disk 50 is started and.V

at the end of a single revolution is automatically stopped. Connected to the disk 50 and to the shaft t5 is a sprocket wheel 62 which is in line with a sprocket wheel 63 on a transverse shaft (Se at the forward end of the trarne. V63 is a chain passing over the sprocket wheels 62 and G3. This shaft Gil mounted in suitable bearings secured to the brackets 65, 66 and 67 mounted on the liront member of the frame. The ratio between the diameters ot the sprocket wheels and 63 is is given a halt revolution for every complete revolution of the shaft d5. Each of the brackets it?, GG and G7, is formed in two parts and between the parts of the sevn eral brackets there are mounted. earns 68,

such .that the shaft dei,

76 adapted to engage respectively with the camsv 68, 69 and Connected tothe rear end of 'the lever 71 is a chain7 7 which extends over a suitable pulley 78 and is connected to the spindle 21. vA chain 7 9 is connected .to the rear end of the lever 72. This chain extends over suitable pulleys 80 and 8l and is connected to, the lever 39 for the wheel 25. A chain 89, is connected to the rear end ot the lever 73. rThis chain eX- tends over suitable pulleys 83 and 84s and 85 and is connected to the lever 39 for the rear wheel 3l.

Eaclrof the cams, G8, 69 and 70, is formed with an active lifting portion 86, an 1inactive sustaining portion 87 and an inactive dropping portion 88. It will therefore be clear that as each cam rotates it engages the corresponding roller to swing the correspending lever and move the corresponding The cams 68, 69and 70 'are angularly I spaced on the shaft so that during rotation the earn 68 first cornes into action then the cam G9 and finally the cam 70. It will be understood from' the foregoing description that the shaft' 64; is rotated through a half revolution at each actuation of the clutch. During one halt-revolution .the active parts oli the cams are brought into engagement with the rollers and the three wheels 19, 25 and 31 are moved successively to cause a successive lift of the adjacent parts of the frame and of the adjacent plowing elements. At the end. of the Hrst halfrevolution the rollers yare still engaged by the cams and the frame parts and plowingl elements are maintainedin lifted positions. During the next half-revolution thefcams successively disengage the rollers and permit the levers tov move and release the frame parts and plowing elements and permit thernto return successively to plowing positions.

rlShe plow as a whole can be hauled in any approved manner as by means of a suitable tractor or traction engine.

Chains 89-89 are provided for the hauling of the plow.

Ywhen the frame sections are in lifted positions. V't will lbe noted that lugs 90 and 91" are provided which serve to hold the wheels agairml swinging whenlthe trarne sections are in plowing position. However, these lugs disengage the wheels when. the frame sections are lifted and free movement of the wheels is therefore possible.

As before pointed out the wheel 19 can he adjusted angularly so as to tend to a greater or less extent to move the plow laterally and to hold the plowing elements up to their work. l
